MIT Program in Polymers and Soft Matter (PPSM) Seminar

Join us this spring as we celebrate Day of Climate at the MIT Museum, a dynamic event dedicated to celebrating the innovative climate work being done at MIT and by passionate learners and educators who are leading work at schools and in their own communities. Inspired by the successful Day of AI, this event aims to bring together a community of like-minded individuals who are committed to addressing the pressing challenges of climate change. It will highlight the significant contributions of MIT researchers, educators, and students in the field of climate science and sustainability.Register for this in-person event!Beyond this event, Day of Climate is a broad new initiative dedicated to equipping K-12 learners and educators with the tools and knowledge to better understand climate change, its impacts, and potential solutions through free, concise, hands-on resources, activities, and curricula. Awarding nearly $125k in grants to support curriculum development to seven groups across the Institute, this effort unites the MIT community and educators, locally and globally, in empowering the next generation to take meaningful action on climate and sustainability challenges.On Wednesday, April 16, Day of Climate will bring together MIT faculty, educators, learners, and local community members to celebrate the incredible efforts of K-12 learners tackling climate change. The event will feature inspiring speakers, including Claudia Urrea, Executive Director of the MIT pK-12 Initiative, Chris Knittel, Director of MIT’s Environmental Solutions Initiative, Pete Bouchard, NBC Boston’s award-winning chief meteorologist, Yashasvi Raj, a PhD student doing cutting edge research in climate science, and a panel of thoughtful educators and youth, providing insights into the latest climate research, innovative solutions, and effective advocacy strategies.Explore the complete agenda for the Day of Climate celebration at the MIT Museum.Save your seat for this in-person Day of Climate event!

Speaker: Wenkui Du (MIT)Title: Rigidity of ancient ovals in mean curvature flow.Abstract:We will discuss the classification of ancient noncollapsed flows as singularity models of mean curvature flow. In particular, I will discuss my recent joint work with Beomjun Choi and Jingze Zhu about spectral rigidity, stability and symmetry of the so-called $k$-ovals in general dimensions. These $k$-ovals belong to the family of ancient ovals (compact non-selfsimilar ancient noncollapsed flows), and are expected to coincide with all the ancient ovals by a recent work of Choi-Haslhofer.

Speaker: Yiannis Sakellaridis (Johns Hopkins University)Title: On the cotangent bundle of spherical varieties.Abstract: I will present a very simple-minded theorem, describing the regular locus of the cotangent bundle of a strongly tempered spherical variety as a "toric embedding'' of the group scheme of regular centralizers. This deepens work of Knop (who described this cotangent bundle up to codimension one), confirms an observation of V. Lafforgue, and can be fed into the argument of Hameister–Luo–Morissey to prove a version of the semiclassical/Dolbeault relative Langlands conjecture. Moreover, this theorem gives a more satisfactory picture about a mysterious symplectic vector space appearing in the dual hyperspherical variety. Part of ongoing joint work with Ben-Zvi and Venkatesh.
